INSOLE CEMENTING MACHINE BACKGROUND OF THE INVENTION There are many kinds of machines for applying adhesive to insoles but insofar as known none is suitable for applying adhesive exclusively to the end portion of an insole as distin guished from machines which apply adhesive to the overall area to the surface and machines which automatically traverse the entire edge of an insole relative to an applicator roll for applying adhesive to the marginal edge thereof. For this reason it is still common practice to daub the adhesive on theend of an insole with a brush. It is accordingly the purpose of this invention to provide a machine for applying adhesive to one or both ends of an insole and to enable controlling the length to which the adhesive is applied. It is also an object to provide a machine which is substantially automatically operable in that the operator need only to place the insole within the machine and such disposition of the insole in the machine will initiate its operation whereupon the insole will be coated and discharged from the machine. Other objects are to provide a machine which will be easily adjustable for application of adhesive to different lengths, to accommodate insoles of different size, which will be reliable and which will require little or no servicing.

SUMMARY As herein illustrated, the machine comprises an applicator roll supported for rotation about a horizontal axis, and a gauge stop supported adjacent the upwardly moving side of the tip plicator roll having a surface normal to a plane tangent to the top of the applicator roll and at a distance therefrom corresponding to the length of the insole to which adhesive is to be applied. There is means for effecting rotation of the applicator roll in a direction such that its surface moves away from the gauge stop and switch means operable when the insole is placed in engagement with the top of the applicator roll and its end pressed against the gauge stop to initiate operation of the machine. A holddown roll is supported above the applicator roll in an elevated position for movement into engagement with the insole resting on the applicator roll and there is means for effecting its movement into engagement with the insole and its rotation substantially simultaneously with the rotation of the applicator roll, and when the tip end of the insole reaches the line of tangency to retract the holddown roll to its elevated position and stop the machine. The applicator roll preferably has two symmetrically disposed adhesive-receiving surfaces located at opposite ends of a given diameter of the roll, each having a leading end and extending peripherally of the roll in a direction opposite to the direction of rotation, and there is means for initially adjusting the roll to position the leading end of one of the surfaces at said line of tangency or optionally to displace it to a predetermined distance with respect thereto.

The drive provided for effecting rotation of the applicator roll rotates it through l80 of rotation each time rotation is initiated.

The apparatus disclosed herein is for precoating the area of an insole at the toe and/or heel with an adhesive which may subsequently be activated during a toe-lasting and/or heellasting operation to secure the lasting margin along these areas.

FIG. 1 illustrates an insole 10 to which adhesive has been applied both at the toe and heel. The present machine is designed especially to enable applying the adhesive to a selected area, for example, to a substantially U-shaped area 12 at the toe and/or a similar substantially U-shaped area 14 at the heel. It is to be understood, however, that the adhesive may be applied to the entire area at the toe and/or heel rather than to the U-shaped area shown and that it may be extended lengthwise of the insole blank to either decrease the area to which the adhesive is applied or to increase it, and especially to control the width of the band across the end from the tip of the toe toward the heel or from the tip of the heel toward the toe and the length of the band along the sides of the insole from the tip of the toe or the tip of the heel rearwardly or forwardly as the case may be.

The machine is provided with a frame 16 generally rectangular in configuration, supported from the floor by four legs 18. The frame in turn supports in a substantially horizontal plane a table 20 and subjacent thereto vertically spaced shelves 22 and 24. A facing panel covers the front of the frame and obviously the sides and backs of the frame may also be provided with enclosing facing panels if desired.

The operative components of the machine comprise an applicator roll 26 mounted from the shelf 22, as will appear hereinafter, with the surface at the top adjacent an opening in the table 20; a holddown roll 28 also supported from the shelf 22 by means extending upwardly through the opening in the table for movement into engagement with an insole resting on the applicator roll 26 at an appropriate time and for rotation in conjunction therewith to effect movement of the insole in a direction to apply adhesive to the area desired and discharge the insole from the machine when the application of adhesive is completed; and means for effecting rotation of the applicator roll and movement of the holddown roll 28 into and out of operating relation therewith comprising a system of air cylinders and valves shown diagrammatically in FIG. 12 which are, for the most part, mounted on the shelf24 within the frame.

Diagrammatically as illustrated in FIG. 2 the insole blank 10 is placed between the applicator roll 26 and the holddown roll 28, the latter at this time being elevated from the applicator roll 26, in tangential contact with the upper surface of the applicator roll 26 and with its end abutting an adjustable gauge stop 30 situated at a distance from the top of the applicator roll corresponding to the distance along the insole blank to which the adhesive is to be applied. Pressure of the end of the sole blank with the gauge stop 30 automatically initiates operation of the machine, as will appear hereinafter, so as simultaneously to bring the holddown roll 28 downwardly into engagement with the insole resting on the applicator roll 26 and effect rotation of the rolls 26 and 28 in opposite directions as indicated by the arrows to retract the insole, that is, back it away from the gauge stop 30 and discharge it so that it slides down an inclined apron 32 mounted in the facing panel into a receptacle situated at the base of the machine for receiving it. Each time an insole is introduced into the machine and initiates operation by engagement with the gauge stop 30, the applicator roll is caused to rotate through 180 and hence adhesive may be applied to two insoles for each complete rotation of the applicator roll 26. By the simple expedient of adjusting the gauge stop 30 relative to the top of the applicator roll, the length of the insole to which adhesive will be applied by backing of the insole away from the gauge stop can be easily increased or decreased, that is, the distance between the line of tangency of the insole with the top of the applicator roll and the gauge stop. The applicator roll has on its surface two cement-receiving surfaces 26a, 26b situated at diametrically disposed positions thereon, the leading ends of which with respect to the direction of rotation are located at opposite ends of a given diameter d-d, as shown in FIG. 3, and each of which extends peripherally thereof in a direction opposite to the direction of rotation. There is indexing means provided in conjunction with the drive for the applicator roll operable to stop the applicator roll following each 180 of rotation with the leading end of one of the adhesive-receiving surfaces at the top. Hence it becomes a simple expedient to control the length of the peripheral surface of the applicator roll which will be brought into engagement with the insole as the latter is backed away from the gauge stop by initially rotating the applicator roll to displace the leading end of the applicator surface relative to the gauge stop in a direction corresponding to that'of the rotation of the applicator roll to decrease the surface available for applying adhesive to the insole or in a direction opposite to the direction of rotation of the applicator roll to increase the surface available for applying adhesive to the insole. Since the applicator roll rotates in a counterclockwise direction, the insole is moved away from or backed away from the gauge stop and during such movement adhesive is progressively applied to the insole from the line of its initial tangential contact with the applicator roll when placed in the machine against the gauge stop to the tip end of the insole. It is within the scope of the invention to employ a single cementreceiving surface or to employ more than two cement-receiving surfaces.

FIG. 6 is an elevation as seen from one side of the machine, to wit, the right side in relation to the front of the machine where the operator would be standing for the purpose of placing the insole between the rolls 26 and 28, the applicator roll 26 being mounted on a horizontally disposed shaft 34 journaled at its opposite ends in bearing plates 36-36 secured to the sidewalls 38-38 of a receptacle 40 adapted to hold a body of molten adhesive. The receptacle 40 is supported by legs 42 from the horizontal shelf 22 and is open at the top.

The applicator roll 26 is supported in the receptacle with its lower part close to but spaced from the bottom and its upper part rising above the open top so that its rotating surface picks up adhesive from the receptacle and carries it upwardly above the open top thereof to a level substantially tangent to the upper surface of a rigid plate 400 fixed transversely of the receptacle to the upper edges of the sidewalls by screwbolts 40b. Suitable doctors of conventional kind may be employed to maintain a uniform layer of adhesive of predetermined thickness on the surface of the applicator roll.

The adhesive is rendered molten and maintained molten by a plurality of heating elements 46 removably fixed in the bottom of the receptacle and the applicator roll is maintained at a temperature sufiiciently high to keep the adhesive on its surface molten as it rises from the receptacle by a heating element 48 mounted in an axial passage 50 provided in the shaft 34 to which current is supplied by means of a pair of rings 52-52 fixed to one end of the shaft for rotation therewith and brushes 54-54 supported on the wall of the receptacle in engagement with the rings, the brushes in turn being adapted to be connected to a suitable source ofclectric power.

The shaft 34 has fixed to its opposite end a sprocket 56 by means of which it is rotated each time rotation is initiated through 180 as will be described hereinafter.

The holddown roll 28, as related above, is mounted above the applicator roll for movement from a retracted position elevated therefrom to a position in engagement with an insole resting on the applicator roll. To this end the holddown roll 28 is secured to a shaft 58 journaled at the forward ends of a pair of transversely spaced rocker arms 60-60. The rear ends of the rocker arms 60-60 are mounted on a horizontally disposed shaft 62, the opposite ends of which are rotatably journaled in the upper ends of bearing blocks 64-64. The lower ends of the bearing blocks are secured to the sidewalls of the receptacle 40. The rear end of each rocker arm 60 is bifurcated as at 66 to enable clamping the rocker arm to the shaft 62 by means of a clamp bolt (not shown) arranged to draw the bifurcated portions of the arm into clamping engagement therewith. The shaft 62 extends through the bearing block 64 at the left side of the machine, as shown in FIG. 7, and has mounted on it a sprocket 66, the sprocket teeth of which lie in the same plane as the sprocket teeth of the sprocket 56. Outwardly of the sprocket 66 there is an arm 68, FIG. 6, which is bifurcated at 70 and clamped to the shaft 62 by means of a clamp bolt 72. The arm 68 is adapted by rotation relative to the axis of the shaft 62 to rotate the shaft 62 and hence to rotate the rocker arms 60-60 in a counterclockwise direction as shown in FIG. 6 to move the holddown roll 28 downwardly into engagement with an insole resting on the applicator roll.

Rotation of the arm 68 is effected by means of a pneumatically operated piston-and-cylinder assembly 74 (FIG. 6). The piston-and-cylinder assembly comprises a cylinder 76, one end of which is pivotally supported by a pin 78 mounted between a pair of spaced upstanding blocks 80-80 fixed to the shelf 22. A piston rod 82 extends from the opposite end of the cylinder 76 and is provided with a clevis 84 for receiving the lower end of the arm 68 and is connected thereto by a pin 85. Extension of the rod 82 from the cylinder will rotate the rocker arms 60-60 in an anticlockwise direction. Withdrawal of the piston rod 82 into the cylinder 76 will rotate the rocker arms in a clockwise direction to elevate the holddown roll 28 from the applicator roll. A cam-actuated valve V3 controls the supply ofpressure to the cylinder 76.

As previously mentioned, a gauge stop 30 is provided for initially positioning the insole for application of adhesive thereto. As illustrated in H0. 6, the gauge stop comprises a vertically disposed toe 86 at the lower end of a vertically rising, rearwardly offset leg 88. The leg 88 is pivotally connected to the upper end of a post 90 by means of a piano hinge 92, one leaf 94 of which is secured by screws 98 to the upper end of the post 90 and the other leaf 96 of which is secured to the upper end of the leg 88 by screwbolts 99. The lower end of the post 90 is provided with a foot 110 by means of which it is adjustably secured to the plate 40a for movement forwardly and rearwardly relative to the applicator roll, as will appear hereinafter. A valve block V is secured by means ofa bracket 100 to the rear side of the post 90 over an aperture 102 of such a size as to expose a valve pin p held distended within the aperture by a spring s. A screw 104 is threaded through the leg 88 in alignment with the aperture in the post 90 and is adjustable therein to a position normally having contact with the spring-backed actuating pin p of the valve when the machine is idle. The spring s holds the leg displaced forwardly at an angle to the post with the toe 86 substantially perpendicular against a limit screw 93 mounted through a hole in the leg and threaded into the post. A locknut 106 is provided for fixing the screw 104 in a predetermined position. The toe 86 is notched at 860 (FIG. 6a) to ride over a ramp 90a fixed to the top of the plate a and has above its lower end a forwardly extending nose 86b. As thus constructed when an end of an insole is pressed against the toe 86 at the lower end of the leg 88, the leg is displaced rearwardly so as to cause the screw 104 to press the actuating pin p inwardly in opposition to the spring s and hence to activate the valve V and to initiate a cycle of operation of the machine as will appear hereinafter. The ramp pushes the end of the insole up into engagement with the toe and the nose prevents it from sliding upwardly too far.

The gauge stop 30, supporting leg 88, post and valve block V are movable as a unit forwardly and rearwardly relative to the applicator roll and to this end the foot at the lower end of the post is secured by a bolt 108 in a slot 112 in the plate 40a.

In conjunction with the gauge stop 30 guide means is provided for centering the leading end of the insole both with respect to the applicator roll and to the gauge stop, the guide means comprising a pair of transversely spaced rollers 200-200 (FIG. 8) mounted to turn on vertically disposed pins 202-202 fixed to the forward ends of transversely spaced arms 204-204. The rear ends of the arms are pivotally mounted on vertically disposed pins 206-206 fixed to laterally extending arms 208-208 which in turn are secured to the post 90. The arms 204-204 have laterally extending shoulders 210-210 recessed to receive springs 212-212 which bias the arms toward each other to hold them engaged with the end of the insole, and to permit them to yield laterally to receive insoles of different transverse width. The arms and the guide rolls supported thereby move forwardly and rearwardly with the gauge stop. The arms 208 are also adjustably secured by means of bolts 209 for adjustment to and from each other transversely of the gauge stop.

The driving means on the lower shelf 24 includes a main drive shaft 114 (FIG. 9) disposed transversely of the machine and journaled for rotation about a horizontal axis in bearing blocks 116-116 fastened to the shelf by screwbolts 118. The right-hand end of the drive shaft 114 extends through its hear ing block and has fixed to it a collar 120. The left-hand end of the drive shaft 114 extends through its bearing block and has fixed to it a collar 122, a cam-carrying plate 124, a sprocket 126 and indexing means 128. The cam plate 124 is adjustably secured to the shaft 114 by a split clamp 125 and bolt 127. The sprocket 126 is located so that its teeth are in the plane of the teeth of the sprockets 56 and 66 and a chain 130 is entrained about the sprockets 126, 66 and 56 so that rotation of the drive shaft 114 by rotating the sprocket 126 will in turn effect rotation of the sprocket 66 and the sprocket 56. The sprocket 56 is fixed to the shaft 34. Hence rotation of the drive shaft 114 in a clockwise direction as seen in H0. 9a effects rotation of the applicator roll in a clockwise direction. The sprocket 66 is free on the shaft 62 and has secured to its hub a gear 132 which meshes with a gear 134 fast to the shaft 58 so that clockwise rotation of the sprocket 66 rotates the gear 132 clockwise and the meshing gear 134 and in turn the holddown roll which is fixed to the shaft 58 in a counterclockwise direction. The rear ends of the rocker arms 60 are, as previously related, fixed to the shaft 62 and when the arms 60-60 are raised or lowered the gear 134 merely rolls around the gear 132.

The drive shaft 114 is rotated through 180", once rotation is initiated and is automatically brought to a stop at the end of said 180 of rotation and will remain so until the next operation is initiated by placing an insole in tangential engagement with the top surface of the applicator roll and with its forward end pressed against the gauge stop 30. Rotation of the drive shaft is effected by means of a pneumatically operated pistonand-cylinder assembly (FIG. 9) comprising a cylinder 142 mounted in a horizontal position on the shelf 24, with one end pivotally secured thereto on a vertically disposed pin 144. A piston rod 146 protrudes from the opposite end of the cylinder and has on it a clevis 148 for receiving an end of a bracket plate 150 to which it is pivotally connected by a pin 152. The bracket plate is attached by means of bolts 154 to the upper side of a rack bar 156 slidably mounted in a longitudinally disposed channel 158 in the shelf. A retainer plate 160 is bolted to the shelf over the channel atone end to hold the rack bar at that end in place and at the: other end is held in the channel by meshing engagement of a gear wheel 162 with its upper toothed side, the gear wheel being rotatably mounted on a stub shaft 164 overlying the rack. The stub shaft is fixed in this position in a bearing block 163, the latter in turn being fastened to the shelf. A gear wheel 1'65 internally ofwhich is a freewheeling, one-direction clutch 166, is mounted on the drive shaft 114 in mesh with the rack bar 156. The clutch 166 provides for imparting rotation of the gear wheel to the drive shaft in one direction of rotation and permits the drive shaft to remain stationary while the gear wheel is rotated in the opposite direction, so that forward movement of the rack bar imparts rotation to the drive shaft 114 and rearward movement or retractive movement of the rack bar is permitted without reversing the direction of rotation ofthe drive shaft.

Due to the fact that the applicator roll and the holddown roll are quite heavy and when once set in motion would tend to continue to rotate, it is necessary to provide means for bringing them to rest without overtravel and this is accomplished by means of an indexing pin 168 (FIG. 9) provided with a conical end 170 for engagement with one of two diametrically disposed conical recesses 172-172 in the peripheral surface of a disc 174 fastened by means of a pin 176 to the drive shaft 114. The index pin 168 is supported in radial alignment with the disc 174 by means of a block 178 with the end opposite the conical end pivotally connected within a clevis 180 by means of a pin 182. The clevis 180 is secured to the protruding end of a piston rod 184 of a pneumatic piston-and-cylinder assembly 186 comprising a cylinder 188 and a rod 184. The opposite end of the cylinder 188 is pivotally connected by a pin 190 to the shelf 24. When the machine is idle the indexing pin 168 is held engaged with the disc 174 so as to hold the drive shaft 114 in a fixed predetermined position. At the instant of initiating operation of the machine, the piston rod 184 is retracted so as in turn to retract the indexing pin 168 to free the drive shaft and thus permit it to rotate. As soon as the rotation is initiated and the conical recess 172 has traveled beyond the conical end of the index pin, the piston rod is extended to hold the index pin against the surface of the disc so that when the next recess reaches the index pin the latter will enter it and stop the drive shaft 114.

As pointed out above, the machine is automatically started by the simple expedient of placing an insole in tangential engagement with the top surface of the adhesive roll with its tip end, whether the toe or heel end, pressed against the gauge stop. Displacement of the gauge stop against the valve V activates the valve V and actuation of the valve V, as shown in FIG. 12, supplies pressure from a pressure line L by way of a conductor C to a valve block V thereby shifting the valve therein so that pressure is supplied from the pressure L through a conductor C to the valve V and through a conductor C the upper end of the cylinder 188 to thereby retract the piston rod 184 and hence the index pin 168. Pressure supplied to the valve V is also transmitted therefrom through a conductor C to the lower end of the cylinder 142 to extend the piston rod 146 therein and hence to effect rotation of the drive shaft 114. A conductor C connected to the conductor C between the valves V and V shifts the valve in the valve block V so that line pressure is supplied through conductor C to the valve V and from thence through a conductor C to the lower end of the cylinder 76 to extend the piston rod 82 therein and hence to lower the holddown roll into engagement with the insole resting on the applicator roll. When the rack bar reaches the end of its forward or driving stroke, it reverses the position of a valve V which is mounted on the shelf in a position to be actuated by engagement of the forward end of the rack bar therewith. Reversing the position of the valve V reverses the position of valve V so that now fluid pressure is delivered through a conductor C to the upper end of the cylinder 142 to retract the piston rod therein and hence to return the rack bar to its initial position. At the same time the half rotation of the drive shaft moves one of the cams 124a, l24b into engagement with the cam roller 124a mounted on a stem extending from the valve V and by such engagement reverses its position thereby supplying pressure through conductor C to the upper end of the cylinder 76 to raise the holddown roll. Pressure supplied to the conductor C is simultaneously transmitted through a conductor C connected to the conductor C to a shuttle valve VS to shift it from right to left and thus to supply pressure through a con ductor C to the lower end of the cylinder 188 to extend the piston rod therein so as to press the index pin against the disc. When the index pin engages the recess in the disc the machine comes to a stop and remains idle until restarted by actuation of the valve V by presentation of another insole to the machine for application of adhesive thereto.

The indexing means 128 comprises a disc 180 containing an opening 181 by means of which it is rotatably mounted on the drive shaft 114 to which there is fastened by means of a rivet 182, or its equivalent, a clamp block 184 provided with a clamp screw 186 by means of which it is clamped to the drive shaft 114. The disc 180 contains peripherally disposed arcuate slots 188a and 188b and behind the disc 180 there is a graduated disc 190 to which there are fixed diametrically disposed threaded studs 192 at radial distances such as to extend through the slots 188a and l88b and on which there are adapted to be threaded clamp nuts 193. The graduated disc 190 is secured by means ofa rivet 195, or its equivalent, to the hub of the sprocket 126. By loosening the clamp nuts on the threaded studs extending through the disc 180, the disc 190 may be rotated relative to the disc 180 to in turn rotate the sprocket 126 relative to the drive shaft 114 to establish a predetermined initial position of the applicator roll at the beginning of the operation. To cause the entire length of the adhesive-bearing surface of the applicator roll to be effective, the adjustment will be made to place the index mark I on the disc 190 opposite the arrow on the disc 180. If only half of the applicator surface is to be employed, the disc 190 is rotated relative to the disc 180 to bring the index mark l opposite the arrow. The effect of this relative rotation is to rotate the applicator roll in an anticlockwise direction to a position such that the midpoint of the applicator surface is at the top and so that when the insole is placed against the applicator roll it will have contact with the adhesive-applying surface at its midlength and hence rotation of the applicator roll will apply only half of the applicator surface to the insole. To provide for initially adjusting the indexing means for applicator rolls of different size, the clamp 184 may be loosened and rotated on the drive shaft 114.

As thus constructed, when the adhesive has been properly melted within the receptacle the operator has only to place an insole in engagement with the upper surface of the applicator roll and push its leading end against the gauge stop whereupon the machine will automatically progressively back the insole out of the machine while simultaneously applying adhesive to that portion of the surface of the insole between its initial line of tangential contact with the applicator roll and the end of the insole engaged with the gauge stop. Having once engaged the insole between the rolls the operator releases it and allows it to be discharged onto the sloping apron at the front of the machine and to be deposited thereby into a receptacle placed at the base of the machine.
